This article mentions that while some people say that 3D printing saves on transportation, it costs a lot for the electricity to heat the materials. It focuses on metal 3D printing which requires a much higher base temperature for the material to melt.

This article advocates for the 3D printer and how much it saves the environment. It mentions a study that found that it is significantly better than traditional manufacturing, but the study also mentions that they need to do more research.

This statement comes directly from a 3D printing company. They say that it is extremely clean to do and leaves almost no waste material. This has to be taken with a grain of salt because there goal is to sell 3D printers to you.

This article is very interesting because it suggests that 3D printing is by far worse than traditional manufacturing and shipping for many reasons including, counterintuitively, a waste of materials. It also suggests that this may be solved by only using 3D printers for prototyping.

This article discusses how the current environmental impact of 3D printing may be worse than traditional measures. If the production goes the right way though, they may become significantly more sustainable.

This article contains an almost two hour lecture containing three separate parts that may offer copious amounts of valuable information for the project.

This article discusses a Michigan Tech study that found that 3D printing can use forty one percent less energy than conventional methods. Combining that with the relative cheapness of some 3D printers and the diagrams to make them, it may be a viable option for many items.

This article discusses the possibility of 3D printing 3D solar panels which may be more efficient than current models. The energy saved by this may be able to offset other environmental impacts that 3D printers have.

This article discusses the inconsistencies in many 3D printers; some hurt the environment significantly more than others while sometimes conventional injection models are better. The studies that found this were only for a few printers so more research needs to be done on the subject.

This article discusses the close-range effects a 3D printer may have on the environment. It mentions Ultra-Fine Particles which could be causing damage to the lungs and brains of any organism.
